FAN.

SPECIFICATION forming part of Letters Patent No. 278,799, dated June 5,1883.

Application filed February 28, 1883. (No modeLl Be it known that'I,FRIEDRICH KINN, of the city, county, and State of New York, haveinvented certain new and useful Improvements in Fans, of which thefollowing is a specification.

This invention relates to improvements in spring-fans, or 'fans of thatclass in which the web of the fan is spread out or opened by a springappliedto the center pivot and one of the released from the handle; andthe invention consists ofa forked handle, to the ends of which iscentrally pivoted a folding web provided with end plates, one of whichis retained in a sliding and spring-acted casing at the base of theforked handle, while the other is adapted to clear said casing. The endplates of the web are connected by a spring that engages a transversestay-pin of the pivoted center disks of web, so as to spread the webinto open position whenever by the release of one of the end plates theconnectingspring is permitted to actuate the web.

In the accompanying drawings, Figure 1 represents a vertical transversesection of my improved fan, shown with the web in open position. Fig. 2is a side view, partly in vertical section, of the fan with the web inclosed position. Fig. 3 is a sectional end view of the fan closed, and 4is a horizontal section on line a, Fig. 1.

Similar letters of reference indicate corresponding parts.

A represents the handle of my improved fan, the upper part of which isforked, so that the space between the forked portion or casing can beutilized for receiving the folded web B. The web is made of radialplaits or folds in the customary manner in fans of this class. The foldsat each end of the web are strengthened by end plates or leaves, I) b,of wood, sheet metal, or other suitable material. The folds of the web Bare held together by disks (2 d, that are cen' trally pivoted to theouter end of the forked handle A, said disks being connected by fixedtransverse pins d d, to which the end plates, 1) b, are applied. The endplates, b b, are made of different length, one being somewhat longerthan the other, both being engaged by a slidby a spiral spring, 6interposed between the pin e and the base of the forked handle, as shownclearly in Figs. 2 and 3. l Vhen the casing O is drawn back away flomthe web of the fan, the shorter end plate, I), is permitted to passclear of the casing and swing around the center pivot of the web to theother side of the handle, by which motion the web is spread into openposition. By returning the end plate the web is folded up again, itbeingengaged in either position by the sliding and spring-pressed casing C,which forms the fastening device for the end plates, b. Both endplates, 1) b, are connected by a rubber or other spring, D, that extendsfirst along one end plate,

I), then between the disks (1 d, and along the opposite end plate, I).The spring D is re tained between the center disks, d (1, by a fixedtransverse pin, located intermediately between the stay-pins d d of thedisks. The springD serves to engage the pin f of the disks whenever theshorter end plate, I), is permitted to clear the casing C, so as toproduce thereby the turning of the center disks and the opening of theweb until the end plate arrives at the other side of the forked handleand is re-engaged by the spring-casing C. By the tension of the spring Don the pin f it is carried with the center disks, (1 (Z, around thepivot-pin (1 until the pin f arrives at a position below the pivot (1but diametrically opposite to its former po- 8 5 sition above the same,as shown in Fig. 1.

The web B is held in open position by the action of the spring and theretaining action of the casing C. For closing the fan the shorter endplate, I), is released again from the casing 0 and swung around thepivot of the web until it arrives at the opposite side of the casing C,

by which motion the spring D is expanded and the center disks, (1 d,with their transverse pin,

returned to their normal position, as shown in 9 5 in Fig. 2. The fan isconsequently thrown into open position with great facility by the actionof the spring on the end plates, b b, and the center disks, (1 cl, bysimply releasing the shorter end plate by drawing back the casing C andallowing it to re-engage the end plate when the web is opened, all ofwhich is accomplished by the action of one hand, as the thumb andindex-finger operate the casing, while the remaining fingers take holdof the hand. For closing, the casing hasto be drawn back and the webreturned into folded position by tak ing hold of the end plate with theother hand.

I am aware that fans which are thrown into open position by the actionof a spring applied to the web and the center pivot of the same are oldand well known. I am also aware that a forked fanhandle in which the webis pivoted to the outer end of the forked portion and arranged with endplates, one of which is retained at the base of the forked portion,while the other is free to swing from one side to the other of thehandle, to be then locked by fasteningdevices of the forked handle, isalso well known, and I therefore distinctly disclaim these features. 7

Having thus described my iiwention, I claim as new and desire to secureby Letters Patent- As an improvement in a fan, the combination of thedisk and web with the elastic spring-band D, the transverse stay-pin f,the end plates, b b, and the sliding casing 0, substantially asdescribed.

In testimony that I claim the foregoing as my invention I have signed myname in presence oftwo subscribing witnesses.
